Any drug which interferes with the action of androgens is therefore assumed, by the lay person, to induce impotence.

While type I is predominant in liver, type II is predominant in prostate, seminal vesicles, epididymes, hair follicles, and liver. Type I 5AR, is present in the sebaceous gland, while type II 5AR is found on the outer root sheath of the hair follicles and dermal papillae.

At all these sites, the testosterone is converted to DHT. Finasteride is a specific and competitive inhibitor of Type II 5—AR, and has therefore a selective action clonazepam for ms pain hair follicles. This explains why relatively small dose of finasteride may be adequate therapeutically.

Semen quality was investigated the medicine finasteride light microscopy to evaluate sperm concentration and motility, sperm morphology by transmission electron microscope TEMpresence of Y microdeletions by PCR, and meiotic segregationby fluorescence in situ hybridization FISH.

TEM analysis revealed altered sperm morphology consistent with necrosis and FISH data revealed elevated diploidy and sex chromosome disomy frequencies. One year after the men had stopped the use of finasteride without receiving any other treatment, a recovery of spermatogenetic process was observed. Motility and morphology improved "the medicine finasteride" the the medicine finasteride pattern did not change.
